Linking Accounts (not tickets)

[LauraLovesDLR]

I just booked our hotel and tickets (yay!) and want members of my party to be able to log in and make payments. How do I do this? I've read about inviting them on My Disney Experience, but that looked like it was just for WDW? We don't have tickets yet to link because it looks like we can't make park reservations until August (the CM I just spoke with said that they anticipate being open normally by Sept). Do I just have to share my account login info or can I somehow link their Disney accounts to mine? Thanks!!
